CAPSULE-MACHINE.

SPECIFICATION forming'part of Letters Patent No. 292,434, dated January 22, 1884. Application filed July 17, 1883. (X0 model.)

.To all whom it may concern:

Be it known that I, .FREDERIcK A. HUBEL, of Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Improvement in Machines for Stripping Gapsules, of which thefollowing is a specification. Figure 1 is a vertical section. Fig. 2 is a perspective of a portion of the machine shown in Fig. 1. Fig. 3 is an elevation, partly in section. Fig. 4 is an enlarged view of one of the clamps shown in Fig. 3. Fig. 5 is a detail view, showing one mode of fastening a moldpin to its plate. Fig. 6 is a horizontal'seetion through Fig. 1. 7

My invention relates to machines for stripping gelatine capsules from the mold-pins on which they are formed; and it consists, mainly, in the combination, with a plate carrying one or more capsule-mold pins so fastened thereto as to be movable laterally, of an inelastic clamp adapted to be closed'upon said pin or pins; and, secondly, in certain combinations, hereinafter pointed out in the claims.

A represents the frame of themachine.

B represents a follower-plate having grooves on its under side to receive and hold theedges of the plate D, and attached to a screw, 0, which works in a nut in the top of frame A and moves plate B. Screw 0 may be turned by an ordinary handwheel or lever attached thereto.

E, E, and E represent mold-pins attached to plate D, so that while firmly held by said plate they are capable of lateral motion. Pins E are attached to spring-wires F, which are socurely fastened to plate E, and pins E E are loosely fastened to plate D, in the manner shown in Fig. 5.

G G represent cleats on two opposite sides of frame A, forming ways in which the ends of the jaws J H slide.

h j represent cross-straps, h being fastened to the jaws H, and j being fastened to the jaws J. All the cross-straps h are fastened by a cross-piece which is pivoted to the connectingrod K, and all the cross-straps j are fastened to a cross-piece which is pivoted to the conneeting-rod L, as shown in Figs. 1 and 6.

M represents a lever pivoted at O to frame fastened in shaft P, and operated by pinions S and lever Q, as shown and described in Patent No. 268,144, granted to me as assignee of Harrison H. Taylor the 28th November, 1882.

S represents a method of securing a moldpin to the mold-canrying plate so that the pin may move laterally, although securely held by the plate.

a (1 represent recesses cut in the meeting edges of jaws J, H, and B. When the jaws are to be used with mold-pins shaped like E E, where their office is merely to remove the capsule aft-er it has been out in another machine, the recesses a a may be shallower than half the diameter of the mold-pin, so that each its circumference; but when they are to be used with mold-pins like E, where their office is to cut the capsule as they pass the annular As moldcarrying plates are now made with the pins rigidly fastened thereto, the clamps or jaws used to remove the capsules must have some spring thereto, or be made in some manner' so that they may move to adjust them selves to the pins, for it is impossible to set the pins in ainumber of plates so that they will register exactly with the jaws of one pullin g-machine but by setting the pins on springwires or loosely fastening them to the plate I am enabled to use rigid inelastic clamps or jaws, the lateral motion of the pinsallowing them to adjust themselves exactly to the jaws.

What I claim as my invention, and desire to secure by Letters Patent, is-
